I bought Turbo Tax Desktop and I am filing multiple tax returns how can I efile 2 separate extensions?

[fanfare]

you must open a return before filing Form 4868.

OR

use the IRS website make a payment page to file 4868.

Select "EXTENSION".

For the Desktop program,  start a new return for each person, then type extend in the search and click on the Jump to link.  Or go to  Other Tax Situations----then scroll down to Other Tax Forms---File an Extension

Extensions form your computer must be printed and mailed.

Or use the online "Easy Extension".
